2. Average traffic (85); MRI (95); blow dryer, subway train (100); power mower, chain saw (105); screaming child (110); rock concert, thunderclap (120), jackhammer, jet engine (130).



3. Noise-induced hearing loss can be caused by a one-time exposure to a loud sound or by repeated exposure to sounds over an extended period of time.



4. Some precautions you can take to protect your hearing include:
   1. Walk away from loud noises.
   2. Turn down the volume.
   3. Limit the intensity of the noise by not standing directly near its source.
   4. Limit the time you expose your ears to loud noises.
   5. Wear earplugs when you're around sounds of 85 dB and above. (Disposable foam earplugs are inexpensive, easy to insert and effective.)
   6. Turn down your CD/cassette player, stereo or iPod.
   7. Cross the street when you hear someone operating a leaf blower.
   8. Wear earplugs at concerts/go to the back of the nightclub or outside to give your ears a break.
   9. Cover your ears with your hands when you're walking past a jackhammer.
5. The lyrics by Beck speak of a ship of noise, resulting in confused instincts, perhaps a loss of balance caused by hearing damage, and he compares the feeling to "blown-out speakers" and ringing in his ears.
